<H3>Commercial Solutions.</H3>
|
|
|
|
<P>Some manufacturers ( eg Seiko, Citizen, Casio ) manufactured
|
|
Wristwatches that could be linked to a computer, ( I remember that in
|
|
1982 Seiko showed a prototype of a wirstwatch TV ( monochrome LCD )).
|
|
<P>
|
|
<P>
|
|
<A HREF="http://www.casio.com">Casio </A> has a broad set of wristwatches, some of
|
|
them could be descibed as Wearables that can display time among other
|
|
things, of interest are the
|
|
<UL>
|
|
<LI>The PC Unite that can exchange data with a computer using
|
|
an infra red link.</LI>
|
|
<LI>The ATC1200-1V Forester features an electronic compass.
|
|
plus thermometer and barometer. I used to own one of these it is a
|
|
great piece of hardware</LI>
|
|
<LI>The Technowear products have different features including voice
|
|
recording, IR remote control, Databank...</LI>
|
|
<LI>The

|
<A HREF="http://205.158.10.200/gps/top.html">GPS </A>watch is one of the most intruiging watch I have

ever seen</LI>

<H3>The Wristwatchcomputer.</H3>
|
|
|
|
<P>In 1998 S. Mann displayed a
|
|
<A HREF="http://www.wearcam.org/wristwatchcomputer/">Wristwatch </A>videoconferencing computer, it runs
|
|
GNU/Linux and uses an XF86 Server, there is a pinhole video camera on
|
|
the watch itself. This device is to say the least impressive, some of
|
|
the software, is
|
|
<A HREF="http://www.wearcam.org/orbits/orbits_v1.08.tar.gz">downlable </A> and GPLed.
|
|
<P>
|
|
<P>It is also possible to use a 4 lines LCD display connected to the
|
|
serial port of your laptop ( numerous paper or online electronics
|
|
magazine offer schematics ).
|
|
<P>
|
|
<H3>PDA type </H3>
|
|
|
|
<P>PDA's seem to be a cheap and efficient way of sending and displaying
|
|
data for a wearable, actually any PDA with a VT100 emulation program
|
|
and a serial link can be used effectively as a terminal ( I have
|
|
successfully used my HP200LX running
|
|
<A HREF="http://www.columbia.edu/kermit">kermit </A>
|
|
<P>as a terminal for my desktop,
|
|
giving me an emergency access to it if the display failed )

|
|
<P>The distinction between obstrusives an non obstrusives ones is not
|
|
from the wearer point of view but from the other people, that is is
|
|
the display forbid to see the wearer's eyes

<H3>Hacks with LEDs </H3>
|
|
|
|
<P>Some people managed to use blinking LEDs in order to retrieve
|
|
information from their device. This is one of the simplest display
|
|
one can imagine : a LED or a row of LED blinking.

<H3>Sony GLASSTRON </H3>
|
|
|
|
<P>Sony sells a device called the Glasstron; in Paris, France the FNAC
|
|
Montparnasse sells the PVD-V30

|
glasstron 55 at 13999F ( this is about US $2333 ).
